2010-02-25drm/nouveau: support version 0x20 displayport tablesBen Skeggs
Not entirely identical to 0x21, the per-encoder table header lacks the third init table pointer. However, our current parsing of the table should work just fine. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-25drm/nouveau: construct a connector table for cards that lack a real oneBen Skeggs

2010-02-25drm/nouveau: fix i2ctable bounds checkingMarcin Slusarz
i2c_entries seems to be the number of i2c entries, so with index equal to this number, we could read invalid data from i2ctable. Fix it. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-25drm/nouveau: fix pramdac_table range checkingMarcin Slusarz
get_tmds_index_reg reads some value from stack when mlv happens to be equal to size of pramdac_table array. Fix it.

2010-02-10drm/nv50: prevent multiple init tables being parsed at the same timeBen Skeggs
With DVI and DP plugged, the DVI clock change interrupts being run can cause DP link training to fail. This adds a spinlock around init table parsing to prevent this. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-09drm/nv40: make INIT_COMPUTE_MEM a NOP, just like nv50Ben Skeggs
It appears we aren't required to do memory sizing ourselves on nv40 either. NV40 init tables read a strap from PEXTDEV_BOOT_0 into a CRTC register, and then later use that value to select a memory configuration (written to PFB_CFG0, just like INIT_COMPUTE_MEM on earlier cards) with INIT_IO_RESTRICT_PROG.

2010-01-14drm/nouveau: less magic DCB 1.5 parsingBen Skeggs
This in the very least matches the parsing of all the previously known entries, and hopefully (at least closer to) correct for any we haven't seen yet. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-14drm/nouveau: assume no nv04 board has a DCB tableBen Skeggs
There's a report of a TNT2 where the DCB table pointer is *not* NULL (it contains a part of a VBIOS data string), and we assume this means a DCB table is present, causing all kinds of hilarity. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-01-14drm/nouveau: trust init table registers are safeBen Skeggs
Apparently the original reason for checking this was there were known register accesses that caused hangs on some chipsets. This was more than likely because of incorrect parsing of previous opcodes, and I hardly think aborting a script half way through is going to be any better (in fact, we have had bug reports where this has been the cause of s/r failures among other things). This patch (which has been in Fedora 12 for a long time now) removes all checking for known register ranges, and just leaves the check to ensure the access is within the mapped aperture to avoid an oops.

2009-12-16drm/nouveau: use drm debug levelsMaarten Maathuis
- Use driver level (0x2) for NV_DEBUG instead of all levels - Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code - Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or NV_INFO Signed-off-by: Maarten Maathuis <madman2003@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org.
